He said this at a press conference in Vilnius, Interfax-Ukraine reports.
"I am convinced that a joint European decision will be much more effective than decisions taken by individual countries. I would like us to decide together as the EU to impose sanctions on Russian and Belarusian agricultural products," Tusk said.
Tusk informed that on Monday, the head of the Polish parliament would initiate a decision on sanctions against agricultural products from Russia and Belarus.
"Today, I will address the Marshal of the Polish Sejm regarding the decision of the Polish Sejm to impose sanctions on Russian agricultural products and Belarusian agricultural products," the Prime Minister assured.
Tusk also believes that toughening sanctions is important, in particular, to ensure the security of the Polish and European agricultural markets in general.
